Pioneer 10" Champion Series Single 4 Ohm Subwoofer - TSW261S4
- Reinforced Cone Structure
Pioneer’s IMPP Composite Cone is newly re-designed to deliver a durable
cone structure for accurate, yet powerful bass. The subwoofer now provides
a single piece cone and drive cone, in addition to a lightweight and rigid
dust cap. This combination offers more rigidity throughout the cone versus
competitors in its class. An extremely durable, yet lightweight cone is vital
to prevent cone failure at high sound pressure levels
- Single Piece Basket
The TS-W261S4 utilizes a highly rigid, fully-enclosed, single piece basket,
derived from our world-record holding SPL competition subwoofers, to help
minimize the vibration throughout the subwoofer and increase the driving force
to the cone, producing louder and rhythmical bass. Improved stiffness of the
basket provides for less sound leaks creating more clear and powerful bass
- New Spider Assembly
With the TS-W261S4, engineers re-designed the spider assembly to allow the
subwoofer to produce more accurate and rich bass. Taking notes from our high-end
SPL competition and Reference Series speakers, the spider is now assembled
onto the spider holder rather than directly on to the basket. Since the cone
is also assembled onto the basket which can cause additional vibration, the
independent structure of the spider holder helps minimize vibration coming
from the cone. This improves playback response, sound outline, and provides
- Cooling and Ventilation
All fast moving parts and friction will create heat and too much heat creates
unwanted audio results. The TS-W261S4 is designed with ventilation holes to
improve air flow and release heat keeping the piston cool for better performance
